It didn't? How much of it did you read? Take a look at the fourth paragraph <the section entitled "Open, Flexible, Expandable Platform":

Sirius Video is available for POWER Onyx, Onyx, and Reality Station graphics workstations.

Additionally, it can be used in POWER CHALLENGE and CHALLENGE server configurations to provide video server capabilities. The most powerful systems in the Silicon Graphics binary-compatible product line are the Onyx and CHALLENGE family workstations and servers.

Please read my question closely, I was not asking about the Sirus Video option, I was asking about the Breakout Box only as stated in the post topic. My questions is, can the breakout box be used with a non sirus video board such as EVO or AV1. Maybe I should have explained better

You probably won't find anything that directly says the Sirius Breakout Box will or won't work with an Octane Personal Video Option. I thought the referenced article covered the issue pretty well, but let me run down why.

Typically breakout boxes are used to provide additional ports that the host adapter doesn't have room for on the bulkhead, and/or to make access to those ports easier <such as with rack-mounted hardware where the host adapter ports are on the rear> - but in either case they 'break out' or extend the functionality of the host adapter.

The brief search mentioned earlier also turned up a number of links to Sirius manuals on SGI's Technical Publications Library. Included in those manuals was an illustration of the Sirius Breakout Box - let's take a look at the BoB <and, for comparison, the the EVO>:

The illustrations <and the manuals if you'd like more detail> provide a number of clues as to why using the Sirius BoB with an EVO <or without the intended host adapter> wouldn't be a trivial undertaking. You'd have to find a way to connect the Octane's PVO to the BoB's Host Interface ports. You'd also need software to control the interactions of the BoB and the PVO via the General-Purpose Interface (GPI).

So, <excluding the issue of when the article was written>, the article doesn't mention the Octane or the EVO for a specific reason, they don't provide a method of extending the functionality of the Sirius host adapter to the Sirius Breakout Box <or even a VME slot in which to install the Sirius adapter>.

The only things I know that you can connect to the "Digital Video Connector" would be an O2 camera, a Miranda VIVO (SDI in/out, rare) or a DVC U2 (SDI and YUV in/out, very rare http://www.unsupported.info/dvc/).
